This invention relates to improvements in window frames and more particularly to a novel and improved device whereby either window frame whereby either the top orl bottom sash may be removed to conveniently clean the outside surface of said sash from the inside of a room.

To enable others skilled in the art to more fully comprehend the underlying features of my invention, reference is had to the accompanying drawing forming a part of the specification in which Fig. 1 is a vertical sectional view throughout the window frame and top and bottom sashes, showing the application of my invention.

Fig. 2 is a front View partly in section showing the position lof the box-like body or casing.

Fig. 3 is a sectional view taken on the line 3 8 of Fig. 1.

Fig. 4 is a perspective view of the box-like body or casing when removed.

Fig. 5 is a cross sectional view of a modified form of the invention.

Fig. '6 is a detail view showing the modilied form of the invention.

Referring now to the drawings wherein like reference numerals designate corresponding parts throughout the several views of the drawing, 5 designates the sill, 6 the stile of a window frame and 7 8 the top and bottom window sashe's respectively having the usual sash weights 9 and sash cords 10 within a recess orcut out portion in' the stile 'located in the frame proper as clearly shown lby Fig. 2 ofthe drawing.

The top and bottom window `sashes operate in the sash guides 11, 12 of the frame formed by the central guide strip 13 extending from the top to the bottom ofI said frame. Referring particularly to Figs. 2 and 4, I

Yprovide aishallow substantially latvboX-like body or casing which is adaptedV tobe set of anyconventional ytype of window frame. Referring particularly to Fig. 3, it will be seen that the widthof the box-like body is substantially the width of the frame.` rIn the form of the invention shown by Fig. 4, the box-like body .or casing consists of an outer wall 14 preferably integra-l with a top and bottom 15, 16 respectively and'end walls 17,

18. The width of the'said bodyV is substane vtially the combined width of the iguides or slightly wider. .The topand bottom is fastened in the recess or cut out portion of the stile by screws or other fastening elements 20. Rivetedor fastenedito the rear wall at 21, I provide a pair of resilient elements preferably in the form of bowed, leaf springs 22, 23 which are adapted to bear against a cover or plate member 24 which is free to move outwardly or within the box-like body. When lthus positioned in the window stile, the guide moved upwardly. and vdownwardly inthe sash guides. The height of the box-like body and .cover orv plate therefor is slightly longerthan the window sash so that when the said win-` dow sash is thrust or urged outwardly against the cover or plate,.the opposite side of the window sash may be released from its guide whereby the sash may be completely removed without detaching or disconnecting the sash cords and sash weights. In other words, either the top or bottom window sashes may be lowered to a position whereby one side thereof being in engagement with the cover or plate ofthe box-like casing, permits the sash to be moved laterally within the casingVK so that the opposite side of the sash is released from the .opposite sash guide of the vstrip 13 retains the cover or plate from mov- -ing inwardly toward the sash frame and consequently the sashes are capable` of being Y lwindowframe. e In a reverse manner the winfdow sash maybe Vreplaced since the cover or l plate is atall timesretained in positionlby "..the central guide stripVv y `fvfln Figs. 'andf Lhave shown a slightly Y' Y Y Y smodiied form-oftheinventionin which the cover or plate26 of the boxlike body is prokvidedrwith'lateral tongues27 adapted to A freelyjpa'ssthrough recesses 28 of thevstile,

yio said tongues being in engagement with iixed ,springs 29 whereby saidcover or plate may be moved outwardly yor inthe same manner as that described in connection with the formof the invention shown by Fig. 4.1 Other means .n

Y 15 may beresorted to for'the same purpose, it

beingunderstood that in all'casesthe cover orY plate must be capable of movement with'- Y in the box-like body or a recess suicientlygto Y e release the opposite side of the sash from the l 20sash guide.r From thisgeonstruction, it will *o be seen that the top' or bottom sash may be thus "entirely removed from the window: Y `frame,forfcleaningf purposes without afliectf.A

ing thevsash cords or sash weight-s.

.v2.75 Y VWhile Ihave shownanddescribed'in l vention-with some degree of particul'arity, it

1 willxbe realized that other modifications landy changesmay be resorted to-nderspecial conditions. I therefore do ynot wish vto be 30 limited and restricted to the exact details "shown anddesoribed. bntreserve the `right to l`rmake such changes and modiications asmay f fairly fall Within the vscope of thesubjeot f Y vmatter now beingclaimed.

i 35 Having shown Aand described myy inven n -tion what I claim asl new and desire to secure l v by Letters Patent is f In a windowv frame 1n c'ombinationwith Y top and bottom window sashes. having sash;

' 4Q guides`,' a shallow box-like body substantially' y l 50 thereof-from its guide.'

the width of said frame vand adapted tobe set ff f within the Stiles of said frame, a freely rvmovl able cover or Vplate forrsaid box-likeV body adapted to normally engage the side of a window lush vwithsaid guides'and held in posiltion by av center strip, and resilient elements j within said body engaging said coverl or plate whereby the top or vbottom sash may be e. y urged laterally to remove the opposite side l In testimony whereof I aix mysignature.
